Question

y=300-5x in standard form

Answer 1

y = 300 - 5x

Standard form:
ax + by = c

y = 300 - 5x
5x + y = 300

Then to find the y-intercept, insert a 0 into the 'x'.
5(0) + y = 300
y = 300
The y-intercept is 300.

To find the x-intercept, insert a 0 into the 'y'.
5x + (0) = 300
5x = 300
x = 60

The x-intercept is 60.

Answer 2

standard form is ax+by=c where a,b, and c are integers and a is usually positive

y=300-5x
add 5x to both sides
5x+y=300

that's standard form

some people say standard form is ax+by+c=0
in that case, it would be 5x+y-300=0
